Toyota is expanding its passenger-side Takata airbag inflator recall campaign by an additional 1.37 million vehicles in the United States. The models covered under this broadened recall are the 2003-2007 Corolla, Matrix, and Lexus SC430; the 2005-2006 Tundra; and the 2005-2007 Sequoia.

In total, Toyota says that this expansion brings the number of its vehicles covered under the Takata inflator recall in the US to 2.915 million. For these latest models, owners will be notified by mail soon. The move is similarto a recent decision by Honda to broaden its recall list.

As with millions of other vehicles covered under these recalls, it's possible for exposure to moisture to cause the inflator to ignite too quickly in an airbag deployment. This can cause shrapnel to be sprayed at occupants. At least seven deaths have been potentially linked to these ruptures worldwide.
